  Reactivity of the RuO bond in η2(O,P)-chelated mono(ether-phospine) (pentamethylcyclopentadienyl) ruthenium(II) complexes

  摘要：

  By treatment of the 16-electron starting compound Cp*RuCl(P similar to O) (1) (Cp* = eta(5)-C(5)Me(5); P similar to O, eta(1)(P)-coordinated ether-phosphine ligand Cy(2)PCH(2)CH(2)OCH(3)) with L = CO (a) and P(OEt)(3) (b), the carbonyl and mixed bisphosphine ruthenium(II) complexes Cp*RuCl(L)(P similar to O) (2a, 2b) are accessible. Chloride abstraction from 2a, 2b with NaBPh(4) leads to the chelated complexes [Cp*Ru(L>(P boolean AND O)][BPh(4)] (3a, 3b) (P boolean AND O, eta(2)(O,P)-coordinated ligand). Cleavage of the Ru-O bond in 3a, 3b with sulphur dioxide results in the formation of the eta(1)-SO2 complexes [Cp*Ru(L)(P similar to O)(eta(1)-SO2)][BPh(4)] (4a, 4b) in which the O2SRu fragment adopts a trigonal planar geometry. In a similar way the Ru-O bond is easily ruptured when [Cp*Ru(CO)(P boolean AND O)][BPh(4)] (3a) is reacted with ethene and phenylacetylene to give the adduct [Cp*Ru(CO)(P similar to O)(eta(2)-C2H4)][BPh(4)] (5a) and the eta(1)-vinylidene complex [Cp*Ru(CO)(P similar to O)(=C=CHPh)][BPh(4)] (6a) respectively.
